Which of the following is not a function of zone of cell differentiation in roots?

Options

(a) Mineral uptake
(b) Water uptake
(c) CO₂ uptake
(d) O₂ uptake

Correct Answer:

CO₂ uptake

Explanation:

Root hair zone (cell differentiation zone) in plants is a specialised structure for water absorption. It is the most efficient water absorption region in roots. In spite of water absorption, root hair zone or root cells are incapabole for photosynthesis because of the absence of chlorophyll but use oxygen for respiration.
